Stranded gamemode dosn't work when unpacked.

When i run the stranded gamemode downloaded right from the workshop it works perfectly, but whenever i unpack it with the GMAD tool, most of its functions don’t work. I also asked my friend to upload his gamemode folder (which works for him) and it doesn’t work for me. The HUD works, but everything else doesn’t. I get the console error when i set up singleplayer:

[ Simple Prop Protection ] 211 props belong to world

Nav File is wrong or something (1)

Attempted to create unknown entity type gms_fists!

When i try to set up a structure i get an error:

Attempted to create unknown entity type gms_buildsite!

So, long story short - gamemode downloaded from workshop works, when i unpack the gamemode it doesn’t work, also a friend sent me his gamemode files which are modified and those still don’t work.

You have missing entities that you didn’t get from the extraction.

There’s a bug with the folder addon system where gamemode entities/weapons/etc will not load.

Is there any way fix or bypass it?

Put everything in your root folder and not addons/

To clarify, this means move the folder addons/gmstranded/gamemodes/gmstranded to root/gamemodes, and not the addons/gmstranded folder

It worked, thank you both a lot!
